Marquez has proved he is the better fighter of the 2. No need for a 5th fight. Pacquiao said there were no distractions in camp, he was knocking down sparring partners and said he would end all doubts about the previous fights and was in good spirits and in turn got knocked down like never before, then knocked out cold it was worse than the Roy Jones Tarver KO when RJJ first got KO'ed cold. That was the beginning of the end for Roy and now this is the fall of Pacman. Pacquiao will never be the same again after that. The iron chin we come to know wasn't there and as a result of that his days at the elite level are over.
